Can't now and this whole week is pretty busy for me. But I noticed this in every scene.B.Y.O.B. wrote: ↑Mon Nov 26, 2018 2:24 pmMight have something to do with russian roulette depth (which is not exposed in the addon).

Maybe we could optimize this - Dade, can you help?
@lacilaci, could you post an example scene that shows this behaviour?
Use high adaptivity to exaggerate the effect = 0.95 and lower warmup and test step to 8, then compare with default 64 for each. I've seen this in multiple builds, curently in linux, but it shouldn't matter.
If you can't reproduce I'll put something together on the weekend maybe. (maybe related, I also always use heavy clamping - maybe affects this issue)
EDIT: I just realized, if I give more room between test step samples, then adaptivity has lesser effect on the image so I guess it makes sense that low warmup and test step samples introduce more noise...
